The weatherman says clear today
He doesn't know you've gone away
And it's raining
Raining in my heart
This verse of "Raining in My Heart" also mentions a weatherman, and the situation as a whole is the same as what's in "Mr. Radio." As the second section of "Mr. Radio" explains: "My wife, she ran away / She left her home." In both songs, a man's lover has left him, which has affected his mood so much that he's a bit indignant at the weatherman's forecast of clear weather.
